This patch adds them back in. When taking the clock from the epll clock (SCLK) the rates on the SPI bus are incorrect, this needs further debugging but the hookup here should be correct and the problem should be else where. The USBCLK case has been dropped because this requires the USB PHY to be enabled.

This big gate isn't very useful to include in our clock tree. If any of the children need to be turned on then the big gate will need to be on anyway. ...and there are plenty of other "big gates" that aren't described in our clock tree, some of which shut off collections of clocks that have no relationship in the hierarchy so are hard to model. "aclk66_peric" is causing earlyprintk problems since it gets disabled as part of the boot process, so let's just remove it. Strangely (and for no good reason) this clock is exported as part of the common clock bindings. Remove it since there are no in-kernel device trees using it and no reason anyone out of tree should refer to it either.
